<p>The planar porous composite structure comprises a reinforcing structure and a matrix. The structure is formed by regular planar structures with openings, formed of continuous yarns (3, 3a, 3b), such as of knitted, woven or braided layers (1a, 1b, 1c, 1d). The pores are formed by the openings (2) of the said structures, such as by the loops of the knitted fabric or by the openings between the weft and warp yarns of a woven fabric, which are aligned by means of aligning means (7) with each other relative to the direction of the plane of the layer. The reinforcing structure is formed by the reinforcing fibres contained in the yarn (3) serving as the structural part of the structure with openings, and the matrix by the matrix material comprised in the yarn (3) of the same structure, the said matrix binding the different yarn sections of the layer (1) that surround single openings and the different layers together, stiffening simultaneously the structure.</p> |
